Hi, my name is Greg, i'm just starting my first cycle, i've been on them for about a week. I was curious as to when I might start seeing negative side effects such as testicular atrophy, baldening, etc. I wasn't having doubts when i first started, but my friends keep telling me that i'm going to become infertile, bald and other nerve-racking things. I only honestly planned on doing them for 2-3 cycles, and was wondering if I would start seeing the negative side effects in this time frame.
